Earlier this month, Sony was sued by a California company called Target Technology. According to Ars Technica, Target Technology claims that the Blu-ray discs manufactured by Sony infringe upon a patent it owns for
reflective-layer materials used in optical discs.
Target Technology, a company that manufactures and sells thin film alloys
for optical discs, has sued Sony in the US District Court for the Southern District of Indiana for violating a patent it holds on
reflective layers used in optical storage media. The patent in question, no. 7,018,696, was filed for in April 2004 and issued in March
2006.
Target Technology's complaint doesn't go into detail on exactly how Blu-ray infringes on its patents, but alleges that
all Blu-ray discs manufactured, sold, and marketed by Sony are infringing. Target Technologies is demanding a jury trial, a declaration
that the patents are valid and enforceable, damages, and an injunction barring Sony from future infringement.
